A novel and efficient palladium-catalyzed C2 arylation of N-substituted indoles with 1-aryltriazenes for the synthesis of 2-arylindoles was developed. In the presence of BF3⋅OEt2 and palladium(II) acetate (Pd(OAc)2), N-substituted indoles reacted with 1-aryltriazenes in N,N-dimethylacetamide (DMAC) to afford the corresponding aryl-indole-type products in good to excellent yields.
开发了一种新颖且高效的钯催化N-取代吲哚与1-芳基三氮烯的C2芳基化反应，用于合成2-芳基吲哚。在三氟化硼乙醚（BF3⋅OEt2）和醋酸钯（Pd(OAc)2）存在下，N-取代吲哚与1-芳基三氮烯在N,N-二甲基乙酰胺（DMAC）中反应，以良好至优异的产率得到相应的芳基吲哚类产物。
